## Why replay_start is rated High

This tool executes a command that changes the state and behavior of the TradingView application (entering replay mode). While not destructive or financial, it actively triggers external operations whose effects depend on provided arguments (the optional date parameter).

From the tool's own definition: "Tool 'replay_start' initiates bar replay mode in TradingView, which is an active operation that triggers a specific workflow state in the application."

## Use case

AI agents invoke replay_start to trigger actions in TradingView MCP Bridge. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
